The Kepler mission, discoverer of 2,321 possible planets around stars in the region near Cygnus (star map) in our Milky Way galaxy, has been extended through 2016 based on a recommendation from the Agency’s Senior Review (pdf document)

Also, Kepler has discovered 2,165 eclipsing binary stars. Binary stars for when most of the mass of the solar system ring condenses or accretes into a single body with enough mass to ignite a fusion reaction, rather than several Jupiter and Neptune sized objects with some rocky planets.

The Kepler Mission has a Quick Guide, which explains the workings of the observatory.

The above diagram illustrates the multi-planet systems found by Kepler. The maps represent the relative sizes of the systems and the relative size of the planets in each system. They are not scaled in relation to the central star.
